73S8014R

Smart Card Interface

Simplifying System Integration™

DATA SHEET

September 2008

DESCRIPTION

The Teridian 73S8014R is a single smart card (ICC) interface

circuit, firmware compatible with 8024-type devices for

configurations where only asynchronous cards must be

supported. It is derived from the 73S8024RN industry-

standard electrical interface. The 73S8014R has been

optimized to match most of the typical Set-Top-Box / A/V

Conditional Access applications. Optimization essentially

involved a smaller pin-count, support for single I/O, and

maximum card current of 65mA (ISO-7816 / EMV

compliance).

The 73S8014R interfaces with the host processor through the

same bus (digital I/Os) as the 73S8024RN, which is

compatible with any other 8024-type IC.

As a result, the

73S8014R is a very attractive cost-reduction path from

traditional 8024 ICs.

The 73S8014R has been designed to

provide full electrical compliance with ISO 7816-3 and EMV

4.0 specifications.

Interfacing with the system controller is done through a

control bus, composed of digital inputs to control the

interface, and one interrupt output to inform the system

controller of the card presence and faults.

The card clock can be generated by an on-chip oscillator

using an external crystal or by connection to an externally

supplied clock signal.

The 73S8014R incorporates an ISO 7816-3

activation/deactivation sequencer that controls the card

signals. Level-shifters drive the card signals with the

selected card voltage (3V or 5V), coming from an internal

Low Drop-Out (LDO) voltage regulator. This LDO regulator is

. Digital

circuitry is powered separately by a digital power supply V

With its embedded LDO regulator, the 73S8024RN is a

cost-effective solution for any application where a 5V

(typically -5% +10%) power supply is available.

Emergency card deactivation is initiated upon card extraction

or upon any fault detected by the protection circuitry. The

fault can be a card over-current, VCC undervoltage or power

supply fault (V

). The card over-current circuitry is a true

current detection function, as opposed to V

voltage drop

detection, as usually implemented in non-Teridian 8024

interface ICs.

The V

voltage fault has a threshold voltage that can be

adjusted with an external resistor network. It allows

automated card deactivation at a customized V

voltage

threshold value. It can be used, for instance, to match the

system controller operating voltage range.

APPLICATIONS

•

Set-Top-Box Conditional Access and Pay-per-View

General purpose smart card readers
